There's definitely something odd about the motion cadence of the MPEG2 file for LUNCHROOM MANNERS when played in Media Player. I tried it on 2 PCs. The file plays back at 23.967 fps, but the motion is stuttery, which usually indicates some difficulty with interlacing. I investigated further...

I loaded the file into VEGAS, and set the project's frame rate to match that of the file. In Vegas, it plays back okay as 24P.

So, this must mean that commonly-installed MPEG2 decoders can't properly handle these particular 23.376 fps files. The codec on this PC is Elecard MPEG2 Demultiplexer --> Ligos MPEG Audio Decoder.

Neither TMPGEnc nor VirtualDub would load the file at all, even though both programs normally load every variant of MPEG and AVI I throw at them.

Thanks for the information.

The 24fps is a different problem than the crashing we see with the streaming films.

The films I've posted come from different sources - some from my commercial DVDs, some from conversions I've done here. The problem films are from the commercial DVDs - but not every film from those DVDs is bad.

I'll do some more investigating.

The alcohol PSAs and MUNCHERS are interlaced 29.97 files. They play great. ALCOHOL DYNAMITE and SOAPY are 24P files. They're good in the 24P Vegas timeline, but they don't play well in Media Player with the codec I have installed. Different MPEG decoders may play the files okay in Media Player, I dunno.

The stubborn files are very useful for creative editing in 24P as they are - but for some reason I have to reduce my Vegas preview window to draft quality to see what I'm doing. Even VOBs from commercial high-quality DVDs don't do this, so I have no idea what's so different about the stubborn files here.

Yes, I am also having the same exact quirks FP is having, but with using WinAmp, using the MPEG-2 CODEC from my installation of PowerDVD (I think). I haven't tried it in Vegas though....
